#include "ltmf.h"

C Syntax	HRESULT IltmfConvert_SaveStillBitmap(pConvert, filename, format, quality, flags, timeout)
C++ Syntax	HRESULT SaveStillBitmap(filename, format, quality, flags, timeout)

Saves a snapshot from the running stream to a file, as a bitmap.

Parameter	Description
pConvert	Pointer to an IltmfConvert interface.
filename	A character string that contains the name of the file in which to save the bitmap.
format	Value that represents the output file format. For a list of possible values, refer to ltmfConvert_StillFormat Constants.
quality	Value that represents the compression quality. This is used only when the Format parameter is ltmfConvert_StillFormat_CMP.
flags	Not used. Pass 0.
timeout	The timeout period, in milliseconds. The function will fail if it was not able to take a sample in the specified time. Use 1 to wait indefinitely until a sample is snapped

S_OK	The function was successful.
<> S_OK	An error occurred. Refer to the Error Codes or the HRESULT error codes in the MediaFoundation documentation.

Comments

This method blocks (does not return) until the timeout occurs or the sample is snapped.

Use the IltmfConvert::SaveStillBitmap function to save a snapshot from the running stream to a file, as a bitmap.

If the passed file name to the Filename parameter is NULL, then the function will return an error.

If the passed file name to the Filename parameter currently exists, then the existing file will be overwritten.
